Sinusitis is categorized as sinusitis without polyps, sinusitis with nasal polyps, and fungal sinusitis. Depending on the cause, different surgical treatments are available. The process includes steps such as opening the sinuses, correcting the abnormal anatomy, and re-establishing ventilation. 1. Sinusitis without nasal polyps: If medication is not effective, surgery can be used. Usually endoscopic surgery is used, and the process includes restoring patency through the sinonasal complex, correcting abnormal nasal anatomy, removing irreversible lesions, and preserving healthy nasal mucosal tissues as much as possible to rebuild the ventilation and drainage of the nasal cavity and sinuses. 2. Sinusitis with nasal polyps: endoscopic treatment is generally used. Under nasal endoscopy and television surveillance, nasal polyps are removed, sinuses are opened, and nasal anatomical abnormalities such as deviated septum and vesicular middle turbinate are corrected. As far as possible to retain the sinus mucosa, rebuild the nasal sinus ventilation and drainage, for the sinus nasal mucosa inflammation to create conditions for benign regression. 3. Fungal sinusitis: non-invasive type of feasible sinus lesion cleanup, the establishment of spacious sinus ventilation and drainage, preservation of sinus mucosa and bone wall. The invasive type should be carried out sinus debridement, removal of sinuses, nasal cavity lesions in the tissue, extensive excision of the mucosa and bone wall of the affected nasal cavity. If sinusitis surgery is needed, please go to a regular medical institution to receive treatment.
